• All living things are made of one or more cells

• All cells come from other preexisting cells

What type of cellular transport goes through a protein channel of a cell membrane FROM AREA OF HIGH CONCENTRATION TO AREA OF LOW CONCENTRATION WITHOUT ENERGY?

• Osmosis

• Active transport

• Passive transport

• Facilitated diffusion

What is osmosis?

• A type of transport that moves molecules from an area of lower concentration to an area of higher concentration an uses ATP (energy)

• A type of transport that moves large molecules from an area of higher concentration to an area of lower concentration using a protein channel

• The process of moving water particles across a semipermeable membrane from the a higher concentration to a lower concentration. The complete process does not require energy to take place

• The process of moving various small particles from a region of higher concentration to a region of lower concentration until equilibrium is reached. This process does not require the use of energy
